Study on Real Water-Saving in Agricultural Region Based on Improved SWAT Model
The water problem in north China is serious. Agriculture water consumption is very high that led to a serious drop in water table. So research on real water saving in the region is very important. The study improved swat2000 model and applied it on the county level real water saving simulation:Use the improved SWAT model,with 2000-2006 meteorologic data and remote sensing evapotranspiration(ET), the Feixiang distributed model is developed based on the soil map, water conservancy and land use from the remote sensing of Feixiang county, Heibei province. Crop pattern change, irrigation scheme change and irrigation water source change scenarios is simulated and real water saving of different scenarios is analyzed. The result of the research can offer reference to the agriculture for real water saving management.
